DS1629 Datasheet 2-wire Digital Thermometer And Real-time Clock

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: DS1629 2-Wire Digital Thermometer and Real-Time Clock.

General Description

SDA - 2-Wire Serial Data Input/Output SCL - 2-Wire Serial Clock GND - Ground ALRM - Thermostat and Clock Alarm Output X1 - 32.768kHz Crystal Input X2 - 32.768kHz Crystal Feedback Output OSC - Buffered Oscillator Output VDD - Power-Supply Voltage (+2.2V to +5V) DESCRIPTION The DS1629 2-wire digital thermometer and real-time clock (RTC) integrates the critical functions of a real-time clock and a temperature monitor in a small outline 8-pin SO package.

Communication to the DS1629 is accomplished via a 2-wire interface.

The wide power-supply range and minimal power requirement of the DS1629 allow for accurate time/temperature measurements in battery-powered applications.

Key Features
